The UK is ready to accept the European Court of Justice as the “final arbiter” on cases of European law covering the bloc’s surveillance and DNA databases, Brussels officials believe. British negotiators will offer the EU’s Luxembourg-based judges a role in order to maintain access to security tools, such as the Schengen Information System and Prum, one source said. Eurocrats say the Prime Minister’s plans for a post-Brexit trade deal is “closer” to the Political Declaration than recent rows suggest.

Non-EU countries, such as Norway and Iceland, can access the bloc's security provisions under the careful watch of the ECJ.

Iceland and Norway's access to the EU's Prum DNA database includes a dispute resolution mechanism, that allows either party to end the pact if they cannot resolve any complaint.

After launching the document, Cabinet minister Michael Gove said: “To be clear, we will not be seeking to align dynamically with EU rules on EU terms governed by EU laws and EU institutions.

“The British people voted to take back control, to bring power home and to have the rules governing this country made by those who are directly accountable to the people of this country, and that is what we are delivering.”
